Description

Forklift attachment

technical field

The invention relates to a forklift attachment.

Background technique

The general structure of the existing forklift has a mast, and the elevating frame moves up and down along the guide rail direction of the mast under the action of the chain transmission mechanism. The fork is fixed on the elevating frame. After shoveling the goods, the unloading operation cannot be realized independently without pallets.

Forklift attachment is an efficient equipment for automatic loading and unloading, stacking and handling. It is a good tool for multi-purpose use of a forklift. Improve and complement the performance of forklifts, to meet the complex and diverse needs of modern logistics storage, handling and handling.

Contents of the invention

The technical problem to be solved by the present invention is to provide a forklift attachment that is easy to use and can realize self-unloading.

In order to solve the above technical problems, the present invention provides a forklift attachment;

It includes at least sliding seats, several curved slide rails, several forks and several driving components;

A number of arc-shaped slide rails are fixedly arranged on the lifting frame of the forklift, and the directions of the several arc-shaped slide rails are in the same direction. Slide blocks matching the arc-shaped slide rails are provided on the sliding seat, and several forks are fixedly connected to the slide seat. And the fork protrudes away from the lifting frame of the forklift;

The driving assembly controls the sliding seat to move along the arc-shaped slide rail, and the driving assembly and the arc-shaped slide rail have a one-to-one correspondence relationship. The driving assembly includes several sliding oil cylinders, and the cylinder body of the sliding oil cylinder is hinged. On the corresponding side wall of the curved slide rail, the end of the piston rod of the sliding oil cylinder is hinged to the sliding seat.

After adopting such a structure, the sliding oil cylinder is used to drive the sliding seat to move along the direction of the arc-shaped slide rail. When the sliding seat and the fork move along the track of the arc-shaped slide rail, a slight flip occurs, and the fork is far away from the side end of the forklift lifting frame. The horizontal height is lower than the height of the other end of the fork, and the goods on the fork slide out of the fork by its own gravity, which can realize the dump truck operation of the forklift.

The forklift attachment also includes a mounting seat, which is fixedly connected to the lifting frame of the forklift, and the arc-shaped slide rail is fixedly connected to the side wall of the mounting seat away from the lifting frame of the forklift; after adopting such a structure, the mounting seat It can facilitate the assembly between the forklift attachment and the forklift, and facilitate daily disassembly and assembly.

The arc-shaped slide rail of this forklift attachment includes the upper swing section and the arc-shaped slide rail body. The inner side of the swing section and the inside of the arc-shaped slide rail body are hinged through a hinge, and the side wall of the swing section away from the hinge direction is connected by a tension spring. It is connected with the mounting seat; a pulley is installed on the sliding block of the sliding seat, and the pulley cooperates with the arc slide rail.

After adopting such a structure, after the sliding seat moves to the upper side of the arc-shaped slide rail, under the action of its gravity, the swing section of the arc-shaped slide rail swings along the hinge, and then drives the sliding seat to swing, and the fork relative to the ground plane swings. The larger turning angle makes it easier for the goods on the fork to slide down and speed up the unloading operation of the forklift attachment.

Detailed ways

Embodiment one

As shown in Figures 1 to 3

The attachment of the forklift includes a mounting seat 1, a sliding seat 3, two curved slide rails 2, two forks 6 and two sets of driving components.

Mounting seat 1 and the lifting frame 52 of the forklift are connected and fixed by bolts, and the lifting frame 52 of the forklift moves up and down along the door frame 51 track of the forklift.

Two arc-shaped slide rails 2 are respectively welded and fixed on the two sides of the mounting seat 1 in the width direction of the forklift, and the two arc-shaped slide rails 2 are located on the side wall of the mounting seat 1 on the side far away from the lifting frame 52 of the forklift. The rail 2 tends to be vertically arranged, and the direction of the two arc-shaped slide rails 2 is consistent. The opening is opposite.

Two slide blocks 31 are arranged on the end face of the sliding seat 3 near the lifting frame 52 side of the forklift, and the two slide blocks 31 are arranged up and down, and the two ends of each slide block 31 extend into the two curved slide rails 2 respectively, The two ends of each slide block 31 cooperate with two arc-shaped slide rails 2, and the fork 6 is welded on the slide seat 3, and the fork 6 stretches out toward the lifting frame 52 direction away from the forklift.

The two groups of driving assemblies and the two arc-shaped slide rails 2 are in one-to-one correspondence. The driving assemblies control the sliding seat 3 to move along the direction of the arc-shaped slide rails 2. The driving assemblies include sliding cylinders 4, and the cylinders of the sliding cylinders 4 The body is hinged on the side wall of the corresponding arc-shaped slide rail 2, and the end of the piston rod of the sliding oil cylinder 4 is hinged with the corresponding sliding seat 3.

When in use, the forklift attachment is installed on the existing forklift, and the forklift attachment can use the fork 6 to scoop up the goods, and the mode of action is consistent with that of the existing forklift; when the forklift needs to unload the scooped goods, The sliding oil cylinder 4 can be started, and the sliding oil cylinder 4 drives the sliding seat 3 to move upward along the arc-shaped slide rail 2. When the sliding seat 3 and its fork 6 move along the track of the arc-shaped slide rail 2, a slight flip occurs, and the fork 6 is far away from the forklift The horizontal height of lifting frame 52 ends is lower than the height of the other end of pallet fork 6, and the goods on pallet fork 6 slide out outside pallet fork 6 by self gravity, the unloading operation of the finished cargo.

Embodiment two

As shown in Figures 4 to 6 (in order to better observe the position of the pulley 32a in the arc-shaped slide rail 2a, the sliding seat 3a and the sliding block 31a are omitted in Figure 6).

The difference between this embodiment and Embodiment 1 is that the arc-shaped slide rail 2a is a segmented structure, and one section of the arc-shaped slide rail 2a is a swing section 21a, and the inner side of the swing section 21a and the inside of the arc-shaped slide rail main body 22a Hinged by the hinge 23a, the swing section 21a swings toward the center of the arc-shaped slide rail body 22a, and the side wall of the swing section 21a away from the hinge 23a is connected to the mounting seat 1a through the tension spring 7a;

A pulley 32a is installed on the slide block 31a of the slide seat 3a, and the pulley 32a cooperates with the arc-shaped slide rail 2a.

The above are only two implementations of the present invention. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the principles of the present invention. These should also be regarded as Belong to the protection scope of the present invention.
